Abstract (en)

Embodiments of the present invention provide a method for learning a media access control address, a network device, and a system. The method for learning a media access control address includes: generating a key value according to a key field of a received packet, and obtaining an index value corresponding to the key value according to the key value; performing a linear random iteration on the index value according to a preset number of iterations; searching, according to an iteration index value obtained during a first iteration, in a MAC address pool for a MAC address corresponding to the iteration index value obtained during the first iteration; and learning a MAC address of the packet according to a search result. In embodiments of the present invention, random distribution of media access control addresses is implemented by using a linear random iteration method, so that a media access control address space can be fully utilized, and the problem of media access control address conflicts can be solved to the greatest extent.
